トカマク型核融合炉プラズマ制御系の適合条件とコントローラ設計 : 機械力学,計測,自動制御

This paper presents control system design for regulating plasma position in Tokamak fusion reactor. The dynamics of plasma position in fusion reactors is essentially unstable ; therefore, the feedback control is required for regulating the plasma position. In the control system, magnetic force is applied to the plasma for regulating when a disturbance comes to sift the plasma position from the equilibrium. The voltage, which is applied to the poloidal coil for producing the magnetic force, is limited to a certain value because of the physical conditions of fusion reactors. The set of disturbances, which are allowed to regulate within the limit of supplied voltage, is clarified in this paper by using the principle of matching. A new method is proposed to obtain a wider class of allowable set of disturbance based on the Youla parameterization of all stabilizing controllers.
